You’re looking for a new lawn mower, you have a fairly large garden with plenty of grass and you want a mower that will make the job as easy and comfortable as possible, so which do you choose? Introducing the new premium 6 Series petrol lawn mowers from STIHL, designed for larger gardens and built with durability and comfort in mind.
The 6 Series range includes the RM 650 and RM 655 models, which are both available with different features depending on what you need from your lawn mower.
RM 650 Lawn Mower
The RM 650 is a powerful petrol mower with a 48cm cutting width, which is powered by a Kohler HD775 OHV SC engine, and, thanks to the clever SmartChoke technology, it’s always easy to start whether the engine is warm or cold. The RM 650 is able to cover an area up to 2000 m2, and all versions feature a super soft grip mono-comfort handlebar, which makes it incredibly easy to access the 70-litre grass catcher box. The handlebar can also be folded over in one simple movement to make the lawn mower much more compact to store.
Not sure whether you want to cut & collect the grass clippings, cut & drop them or mulch them back into the lawn? The RM 650 lawn mower features an innovative 3-in-1 cutting blade. So if you want to cut & collect, simply leave the grass catcher box on the mower. If you want to cut & drop, just remove the box. And if you want to mulch, you just need to fit the mulch plug which comes with the mower. The choice is yours!
Once you’ve decided how you want to mow, it’s really easy to adjust the cutting height of the lawn mower too using the spring-loaded central cutting height adjuster.
The RM 650 is available either as the RM 650 T or the RM 650 V version, which both help to take the effort out of mowing your lawn by propelling the mower forward. The RM 650 T has one-speed drive, which is great if you have a sloped garden where you need to push the mower uphill.
Alternatively, the RM 650 V features Vario-speed drive, which means you can adjust the speed between 2.6 – 4.6 km/h, using the control lever on the handlebar. This means you can perfectly control the speed to suit you, which is ideal if your garden has obstacles to mow around.
RM 655 Lawn Mower
If your lawn is a little larger, you could always consider one of the RM 655 mowers, which can cover lawns up to 2500 m2 with the 53cm cutting decks.
They also feature the same handy mono-comfort handlebar, the 3-in-1 cutting blade option and the spring-loaded central cutting height adjustment mechanism too. There are three different versions of the RM 655 mower – the RM 655 V, the RM 655 VS and the RM 655 RS.
The RM 655 V is simply a bigger version of the RM 650 V, using the same Kohler HD775 OHV SC engine, with Vario-speed drive. The RM 655 VS features the same Vario drive speed as the RM 655 V, but with the added bonus of Blade Brake Clutch technology. So what does this do? Simply put, it allows the engine of the mower to continue running while the blade is disengaged. This lets you empty the grass catcher box without having to stop and restart the mower, so you’ll be able to mow your lawn more quickly.
The final mower in the 6 Series range is the RM 655 RS, which is a professional rear roller lawn mower, and you can find out more about it in our dedicated article here. You can also see the STIHL 6 Series lawn mowers in action here:

This is from the Stihl website…..RM 655 VS Petrol Lawn Mower: High performance petrol lawn mower with blade brake clutch
The STIHL RM 655 VS petrol lawn mower has a powerful Kohler engine. With its Vario drive and a cutting width of 53cm/21″, it is the perfect mower for mowing large lawns. The central seven-setting cutting deck can easily be adjusted from 25 to 85 mm. During lawn mowing, the speed of the powerful engine always remains constant, even during changes in the drive speed, ensuring the mower is always working at its best. The mono-comfort handlebar gives uninterrupted access to the grass catcher box, making it so much easier to empty when full. For even more convenience, the blade brake clutch of the RM 655 VS allows you to disengage the blades with the engine running so you don’t have to restart after emptying the grass box. The fold-open 70l grass catcher box features an intergrated level indicator which lets you know when the grass needs emptying. With this petrol lawn mower, cutting large lawns will no longer be a boring chore. The RM 655 VS comes with a 5 year extended domestic warranty (subject to registration and annual servicing).
So which is it, a Kholer or a Briggs and Stratton engine????
You don’t make buying easy when i find glaring inconsistency like this.
Hello, thank you for your comment and we apologise for any confusion. At the time of writing, the RM 655 VS was launched with a Briggs and Stratton engine, however, there have been a number of changes since 2019 and it now has a Kohler HD775 OHV SC engine. In cases of doubt, the main website should always have the most up-to-date information but we will get the information above updated. Thanks, STIHL GB
